2011-02-04USB: gadget: f_fs: even zero-length packets require a bufferMarek Szyprowski1-0/+8
Some UDC drivers fails to queue a request if req->buf == NULL even for ZLP requests. This patch adds a poisoned pointer instead of NULL to make the code compliant with the gadget specification and catches possible bug in the UDC driver if it tries to dereference buffer pointer on ZLP request.

2011-02-04USB: HCD: Add driver hooks for (un)?map_urb_for_dmaRobert Morell1-2/+20
Provide optional hooks for the host controller driver to override the default DMA mapping and unmapping routines. In general, these shouldn't be necessary unless the host controller has special DMA requirements, such as alignment contraints. If these are not specified, the general usb_hcd_(un)?map_urb_for_dma functions will be used instead. Also, pass the status to unmap_urb_for_dma so it can know whether the DMA buffer has been overwritten. Finally, add a flag to be used by these implementations if they allocated a temporary buffer so it can be freed properly when unmapping.

2011-02-04USB: usbmon: fix-up docs and text API for sparse ISOPete Zaitcev1-0/+3
This is based on a patch that Alan Stern wrote. It did the same simple thing in both text and binary cases. In the same time, Marton and I fixed the binary side properly, but this leaves the text to be fixed. It is not very important due to low maxium data size of text, but let's add it just for extra correctness. The pseudocode is too much to keep fixed up, and we have real code to be used as examples now, so let's drop it too.

2011-02-04USB: EHCI: Rearrange create_companion_file() to avoid GCC-4.6 warnings.David Daney1-2/+3
In create_companion_file() there is a bogus assignemt to i created for the express purpose of avoiding an ignored return value warning. With pre-release GCC-4.6, this causes a 'set but not used' warning. Kick the problem further down the road by just returning i. All the callers of create_companion_file() ignore its return value, so all is good: o No warnings are issued. o We still subvert the desires of the authors of device_create_file() by ignorning error conditions.

2011-02-04USB: EHCI: Cleanup and rewrite ehci_vdgb().David Daney1-3/+1
The vdbg macro is not used anywhere so it can be removed. With pre-release GCC-4.6, there are several complaints of variables that are 'set but not used' caused by the ehci_vdbg() macro expanding to something that does not contain any of its arguments. We can quiet this warning by rewriting ehci_vdbg() as a variadic static inline that does nothing. Signed-off-by: David Daney <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2011-02-04USB host: Move AMD PLL quirk to pci-quirks.cAndiry Xu10-222/+311
This patch moves the AMD PLL quirk code in OHCI/EHCI driver to pci-quirks.c, and exports the functions to be used by xHCI driver later. AMD PLL quirk disable the optional PM feature inside specific SB700/SB800/Hudson-2/3 platforms under the following conditions: 1. If an isochronous device is connected to OHCI/EHCI/xHCI port and is active; 2. Optional PM feature that powers down the internal Bus PLL when the link is in low power state is enabled. Without AMD PLL quirk, USB isochronous stream may stutter or have breaks occasionally, which greatly impair the performance of audio/video streams. Currently AMD PLL quirk is implemented in OHCI and EHCI driver, and will be added to xHCI driver too. They are doing similar things actually, so move the quirk code to pci-quirks.c, which has several advantages: 1. Remove duplicate defines and functions in OHCI/EHCI (and xHCI) driver and make them cleaner; 2. AMD chipset information will be probed only once and then stored. Currently they're probed during every OHCI/EHCI initialization, move the detect code to pci-quirks.c saves the repeat detect cost; 3. Build up synchronization among OHCI/EHCI/xHCI driver. In current code, every host controller enable/disable PLL only according to its own status, and may enable PLL while there is still isoc transfer on other HCs. Move the quirk to pci-quirks.c prevents this issue.

2011-02-04USB: Gadget: Initialize wMaxPacketSize if not already setJassi Brar1-0/+7
Currently, for ISO and INT, a protocol driver must chose the value for wMaxPacketSize arbitrarily. The value may be too low, resulting in lesser than efficient operation or high enough to not work with all UDC drivers. Take un-initialized wMaxPacketSize as a hint to provide maximum possible packetsize for the selected endpoint. The protocol may then choose a value not bigger than that.

Added mct_u232_ioctl (implements TIOCMIWAIT command), mct_u232_get_icount (implements TIOCGICOUNT command) and mct_u232_msr_to_icount functions. MCT U232 P9 is one of a few usb to serail adapters which converts USB +/-5v voltage levels to COM +/-15 voltages. So it can also power COM interfaced devices. This makes it very usable for legacy COM interfaced data-acquisition hardware.

2011-02-03USB: fix race between root-hub resume and wakeup requestsAlan Stern1-1/+1
The USB core keeps track of pending resume requests for root hubs, in order to resolve races between wakeup requests and suspends. However the code that does this is subject to another race (between wakeup requests and resumes) because the WAKEUP_PENDING flag is cleared before the resume occurs, leaving a window in which another wakeup request might arrive. This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING flag after the resume instead of before it. This fixes Bugzilla #24952.

If we leave via the 'fail' label due to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope without having been assigned to anything, so we'll leak the memory we allocated.

Where as it is possible for dma code to reject the usb request later at ->channel_program() called from txstate()/rxstate() For example ->channel_program in tusb6010_omap.c: static int tusb_omap_dma_program(struct dma_channel *channel, u16 packet_sz, u8 rndis_mode, dma_addr_t dma_addr, u32 len) { ... if (unlikely(dma_addr & 0x1) || (len < 32) || (len > packet_sz)) return false; ... if (dma_addr & 0x2) return false; ... } In this case, usb request will be handled in PIO mode which renders dma mapping operations unnecessary. This patch adds an api to allow dma code to indicate incompatibility with usb request. Gadget musb driver call this api, if available, before dma mappings to avoid any unnecessary mapping operations.

2011-02-01usb: musb: maintain three states for buffer mappings instead of twoMian Yousaf Kaukab2-21/+32
If dma buffers are mapped by a higher layer, with a boolean musb_request.mapped it is still possible to call dma_sync_single_for_device() from musb_g_giveback(), even if txstate()/rxstate() has called unmap_dma_buffer() before falling back to pio mode. Moreover, check for musb_ep->dma is moved within map_dma_buffer() so where applicable checks for it are removed. And where possible, checks for is_dma_capable() are merged with buffer map state check. Signed-off-by: Mian Yousaf Kaukab <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>
2011-02-01usb: musb: disable double buffering when it's brokenFelipe Balbi4-8/+28
We know that blackfin doesn't support double buffering feature as of today. So we add a flag set by musb_platform_init() to forcefully disable that feature. Such flag is created and marked as deprecated to force us to find a solution for the missing double buffering support on blackfin. Signed-off-by: Felipe Balbi <[email protected]>

2011-02-01usb: musb: core: fix IRQ checkSergei Shtylyov1-1/+1
musb_probe() only regards 0 as a wrong IRQ number, despite platform_get_irq() that it calls returns -ENXIO in that case. It leads to musb_init_controller() calling request_irq() with a negative IRQ number, and when it naturally fails, the following is printed to the console: request_irq -6 failed! musb_init_controller failed with status -19 Fix musb_probe() to filter out the error values as well as 0.

2011-02-01usb: musb: fix kernel panic during s2ram(v2)Ming Lei1-7/+1
This patch fixes kernel panic during s2ram, which is caused by the below: - musb is not put into drv data of musb platform device if CONFIG_USB_MUSB_HDRC_HCD is defined - glue layer driver always get musb instance via platform_get_drvdata. The patch fixes the issue by always puting musb into drv data of musb platform device, which is doable even the platform device is a host controller device.

2011-01-22USB: serial: handle Data Carrier Detect changesLibor Pechacek7-40/+47
Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again.
